Abstract
The utility model relates to the technical field of welding gun cooling devices, in particular to a welding gun cooling pipe, which comprises an outer pipe and an inner pipe. At least one water inlet through groove and at least one water return through groove corresponding to the water inlet through groove are axially disposed in the outer pipe, two side walls of each water inlet through groove and two side walls of each water return through groove are all arc-shaped walls, the inner pipe is fixedly mounted in the outer pipe, a water inlet passage is formed between the water inlet through groove and the inner pipe, and a water return passage is formed between the water return through groove and the inner pipe. The welding gun cooling pipe is simple in structure and convenient in use, can realize circulation cooling due to the fact that cold and hot water pipes are distributed alternatively, and is uniform in cooling, fine in cooling effect, smoother in circulation of cooling water and small in resistance.
Description
Technical field
The utility model relates to welding gun cooling unit technical field, is a kind of welding gun cooling tube.
Background technique
During water cooled welding torch work, the temperature of its soldering tip reaches 2000～3000 ℃, in order to guarantee its proper functioning, needs water composite cooling pipe to come water flowing to cool off.During cooling, water enters from intake tunnel, through heat exchange, after cooling off, flow out from backwater channel, thus the cooling of realization Butt welding gun soldering tip.The water composite cooling pipe of existing welding gun all is composite pipe usually, and there is following problem in the conventional composite pipe: after 1, copper pipe was processed by milling machine, its surface finishment was relatively poor, is unfavorable for the circulation of gas, water; 2, because of milling machine can only mill a groove at every turn, each product needed is repeatedly processed just and can be finished, thereby the precision of processing is low, cumulative error is bigger, is unfavorable for that the up-to-standard rate of the assembling of finished product and product is lower; 3, be subjected to the restriction of milling machine performance (length), the length of each processed product is shorter, thereby output is lower, and the manufacture cycle is long, the cost of production height; 4, use milling machine to add trade union and produce a large amount of copper scales, cost of material strengthens, and causes the serious waste of human and material resources, resource; 5, product adopts the mode of transition fit to assemble.Be subjected to the influence of machining tolerance, can produce the gap when outer sleeve and barrel assembling, the hot water or cold water can gang up (being commonly called as short circuit) during use, and cooling effect is poor.
Summary of the invention
The utility model provides a kind of welding gun cooling tube, has overcome the deficiency of above-mentioned prior art, and it can solve the problem that above-mentioned prior art exists.
The technical solution of the utility model is achieved like this: the welding gun cooling tube, comprise outer tube and interior pipe, in outer tube, have vertically at least one the water inlet groove and at least one and with water inlet groove corresponding backwater groove, two sidewalls of each water inlet groove and each backwater groove are arcwall, interior pipe is fixedly mounted in the outer tube, form intake tunnel between water inlet groove and the interior pipe, form backwater channel between backwater groove and the interior pipe.
More than water inlet groove and backwater groove are respectively two, and the cross section of each intake tunnel and backwater channel is all identical.
More than axial restraint is equipped with five guide plates in water inlet groove and the backwater groove.
More than be axially installed with seal ring between outer tube between adjacent water inlet groove and the backwater groove and the interior pipe.
The utility model is simple in structure, and is easy to use, owing to adopt hot and cold water pipe arranged alternate, and the cooling that can circulate like this, and cooling is evenly, good cooling results, and the cooling water circulation is more smooth and easy, resistance is little.
Description of drawings
Fig. 1 looks sectional structure chart for master of the present utility model.
Among the figure, 1, outer tube, 2, guide plate, 3, the water inlet groove, 4, interior pipe, 5, sidewall, 6, seal ring, 7, the backwater groove.
Embodiment
As shown in Figure 1, the welding gun cooling tube, comprise outer tube 1 and interior pipe 4, water inlet groove 3 and at least one and water inlet groove 3 corresponding backwater grooves 7 that at least one is arranged in outer tube 1 vertically, two sidewalls 5 of each water inlet groove 3 and each backwater groove 7 are arcwall, interior pipe 4 is fixedly mounted in the outer tube 1, form intake tunnel between water inlet groove 3 and the interior pipe 4, form backwater channel between backwater groove 7 and the interior pipe 4, like this, cold water enters into from intake tunnel and flows out from backwater channel after the welding gun soldering tip partly fully cools off again, its cooling evenly, good cooling results, the cooling water circulation is more smooth and easy, resistance is little, and the arc wall energy reduces resistance to water-flow.
As shown in Figure 1, as required, water inlet groove 3 and backwater groove 7 are respectively two, and the cross section of each intake tunnel and backwater channel is all identical.
As shown in Figure 1, for the water of giving circulation gives leading role, make the circulation of water more smooth and easy, cooling effect is better, and axial restraint is equipped with five guide plates 2 in water inlet groove 3 and the backwater groove 7.
As shown in Figure 1, in order to increase sealing, be axially installed with seal ring 6 between outer tube 1 between adjacent water inlet groove 3 and the backwater groove 7 and the interior pipe 4.
